BQN is a modern APL-derived array programming language with infix notation, built-in multidimensional array operations, and first-class functions. The repository hosts its self-hosted compiler, specification, documentation, and a browser-based REPL, with a low-dependency C bytecode implementation (CBQN) for offline use.

Use cases

  • learn array programming in an APL-like language
  • script and prototype with concise array notation
  • number crunching on multidimensional arrays
  • run APL-style code in the browser via a REPL
  • embed an array language via C FFI

When to choose

  • you want a modern, cleaned-up APL with consistent semantics
  • you work with multidimensional arrays and want built-in array operations
  • you want good documentation and tutorials for learning array programming

When to avoid

  • you need a mature package manager and library ecosystem
  • you need multi-threaded or distributed performance
  • your team requires mainstream syntax and hiring pool
